Fu Fuai

Fu Fuai (died 645 AD) was a Tang Chinese general during the Goguryeo-Tang War. In 645 AD, he supervised the construction of a siege mound during the Siege of Ansi, but he abandoned it as the Goguryeo forces destroyed it and killed the vast majority of his men. Fu Fuai fled back to the main force, where a furious Emperor Taizong of Tang slashed him across the throat with his sword, killing the cowardly general.
